Apparently, the latest set of rumors that surround the so-called Google Watch is this – this smartwatch is currently going through the final optimization course, and will most probably be centered around Google Now functionality. Of course, an interesting point to take note would be the possibility that a slew of Google Glass functionality could arrive in the alleged Google Watch, but that is one rumor that we ought to take with a pinch of salt as time will reveal all. Other than that, the Google Watch will also supposedly rely on Bluetooth 4.0 with the Ultra Low Energy standard in order to communicate with your phone, hence allowing it to last longer while it is in action.
